Question 7 (ii) (iii) (iv) (v) (vi). Consider the economy with following components of aggregate expenditure: Consumption function: C 25+0.8 Y Investment function: I=30 Government Expenditures: G=10 Export function: X=7 Import function: M=2+0.2Y There are no taxes, so YD = Y What is the equation of aggregate expenditure function in this economy? Solve mathematically for aggregate expenditure and real GDP. What is induced expenditure in equilibrium? What is the multiplier for this economy? If investment increases by 10, how much will GDP increase? Calculate the new level of real GDP after this increase in investment. (viii). Show the initial and the new equilibrium on a graph.
Assume an economy has a consumption function of C = 0.87 (Yd) + $270.18. Additionally, this economy has investment spending = $878.78, government purchases $299.38, taxes = $111.59, exports = $209.28, and imports $289.40. What is the equilibrium level of GDP based on this information? Round your answer to two digits after the decimal. =

The aggregate expenditures of the hypothetical country shown includes $2 billion in investment expenditures, $3 billion in government expenditures, and $1 billion in exports. At a real GDP of $18 billion, consumption expenditures less imports equal $12 billion and imports equal $2 billion. Use this information to graph the aggregate expenditures (AE) function. Assume autonomous consumption and autonomous imports are $0.

The following graph shows three total expenditure lines for an economy at three different price levels. AE10 corresponds to the price level of 130; AE110 corresponds to the price level of 110; AE10 corresponds to the price level of 150. The black line (which starts in the bottom left corner) is a 45-degree line illustrating the set of points for which real GDP and total expenditure are equal.

Q3 In a simple macroeconomic model, the value of national income Y may be found by solving the system: G= 250 (government expenditure) T= 50 (taxation) I= 100 (planned investment) C = 0.75Yd + 150 (consumption) where disposable income Yd = Y – T. (a) Calculate the equilibrium level of national income. (b) Calculate the total increase in government expenditure and investment needed to increase the equilibrium level of national income by 20.
